In 510 BC, after a 70-day siege, the army of Croton did something no Greek army had done before: they diverted the Crati river to flood Sybaris entirely. Not burned. Not sacked. Drowned under water and silt, deliberately erased. The city wasn't rediscovered until 1932. Walk to the far eastern section of the excavation, near where the Crati river channels run today, and find the water management display showing the river's historical course. Stand at the edge of the excavated area and look toward the horizon - you're looking at ancient Greek engineering as a weapon of total destruction. Romans later built Copia on top, then Thuriae on top of that. Three cities stacked, the original buried deepest.
🔄 BACKUP: The museum at the same site has archaeological stratigraphy diagrams showing the three urban layers. Find the one showing the Sybarite stratum - it's the deepest.
